I originally postet this into the Fedora bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=843836
Currently gracefully shutting down guest vms on host shutdown does not work on
Fedora 17, the guests are killed hard on system shutdown.
The reason is systemd considers libvirt-guests.service to be stopped when the
system is running:
$ systemctl status libvirt-guests.service
libvirt-guests.service - Suspend Active Libvirt Guests
Loaded: loaded (/usr/lib/systemd/system/libvirt-guests.service;
enabled)
Active: deactivating (stop) since Fri, 27 Jul 2012 15:47:31 +0200;
2min 48s ago
Process: 1085 ExecStart=/etc/init.d/libvirt-guests start
(code=exited, status=0/SUCCESS)
Control: 1150 (libvirt-guests)
CGroup: name=systemd:/system/libvirt-guests.service
└ control
├ 1150 /bin/sh /etc/init.d/libvirt-guests stop
└ 2257 sleep 1
libvirt-guests.service is defined as type "simple" in systemd (the default).
That means systemd will shut down the service when the start executable is
terminated after starting is done. Systemd will not call stop again on system
shutdown because it thinks it is already stopped.
The solution is to define it as type "oneshot" and set the flag
"RemainAfterExit". Then systemd will consider the service as active after
startup and will call the stop function on host shutdown.
